The leaders of the US, the UK and Spain are to hold an emergency summit on 16 March to discuss the impasse in the UN Security Council over a second resolution on Iraq. The three co-sponsored the draft resolution which would have given Iraq until 17 March to prove it was complying unconditionally with its disarmament obligations or face war. However, despite intense diplomacy the three have been unable to come up with a second resolution acceptable to the majority of Security Council members. US President Bush, UK Prime Minister Tony Blair and Spanish Prime Minister Jose Maria Aznar will meet in the Azores to discuss how to procede, according to White House spokesman Ari Fleischer. On 13 March, Washington appeared to backtrack from insistence on forcing a vote so that Security Council members would have to 'show their cards' on the Iraq crisis. Secretary of State Colin Powell raised the possibility that no vote would be called.
